Ms Alice-Mary Higgins:

We are due to have an event on 25 November 2014 at which we will be examining that issue collectively as an alliance. We are also considering the longer-term questions on the balancing of principles, such as the polluter-pays principle and the principles of progressivity. I will let Mr. Ewing elaborate on that. It would not be appropriate for us to represent others when we have not consulted them on a final position.
